Growing Marijuana In California

Are you confused about the rules on growing weed in California? Still can’t seem to find information about how many weed plants you can grow? I’m pretty sure that is by design.

Please note: ILGM is NOT a legal adviser. Information contained in this website is intended as general introductory information only. The information contained on this website is not legal advice. It should not be construed as legal advice and should not be relied upon as such.

Being that marijuana legalization is still pretty new, in many states the rules are quite vague. I’m no lawyer, but I have gathered some info in the hope that you’ll learn what you need to know about marijuana growing laws in California. However, if you need more information, you probably should talk to a lawyer.

I’ll also share some basics on California’s medical marijuana program as well as a timeline of all the changes in marijuana law. It isn’t always about the rules, though, that’s why you will find some weed growing etiquette advice as well.

Keep reading to learn about growing in the great state of Cali.

First, a summary:

California can now legally grow up to six marijuana plants at home, including all of the harvest from those plants.

That means:

Every adult Californian can now legally grow marijuana. Based on California’s history, this is likely an event that was destined to occur. Still, before you get started growing; there are some rules.

Here’s what you should know:

  1. The minimum age is 21
  2. Possess no more than 6 plants at a time
  3. Grow only where you live, where it cannot be seen and lock it
  4. Carry no more than 28.5 grams, leave the rest at home
  5. Cities can prohibit outdoor growing, but not indoor growing
  6. If you’re in trouble with the law, get a cannabis lawyer

    The Finer Details of Growing Laws in California

    Of course, those were the basics. Now I’ll go into more detail about each point.

    The minimum age is 21

    Marijuana is now treated similarly to alcohol, so no underage growing. To clarify, while teenagers may love growing weed

    Hey, it’s a fun science project.

    The current law is clear that it is an adult sport.

    Possess no more than 6 marijuana plants

    This is probably the clearest part of the new law. It says six plants, regardless of their stage in the growing process. Many other states allow adults to have additional plants that are not already flowering – California does not.

    You can grow maximum 6 marijuana plants in california

    Without a doubt, this rule is likely due to environmentalists’ concerns over widespread home growing impacting the water supply. Therefore, everyone needs to be conservative in their weed growing.

    Once again, a single person can only grow six plants. While this rule may be a bummer to some, it’s not that big of a deal. After all, do you know how much weed you can yield from six plants?

    You’ll be fine – especially if you use advanced growing techniques like those taught in this blog… Plan ahead and store your weed well, and you’ll have plenty to cook with.

    When limited to six plants you want to consider which plants to grow.

    Keep your grow personal

    Another key point: just because growing is legal in California, it’s still a personal privilege that should be kept private.

    Sorry, guys, it’s still not a good idea to show off your grow.

    In a similar fashion, you should only be growing in your own home or on your property. People should not be able to see your plants unless you live in a place that doesn’t care and it’s just your neighbors – and they don’t mind.

    28.5 gram is the maximum ammount
    28.5 gram is the maximum amount

    For the most part, it seems reasonable that you should be able to grow in your backyard, however, even that may be a problem. If you are growing openly in your backyard and you live next to someplace public, like a park, that is, in fact, illegal.

      28.5 is the magic number

      Great news; you can grow as much weed as you want from your six plants!

      But there’s a catch. You can’t carry it around.

      At any given time, you can only have 28.5 grams of marijuana. Seeing that this equals an ounce, this should not be a problem for most people. On the positive side, this does not apply to weed from your personal harvest. You can keep all of that.

      However, if you give away any of it, you can only take 28.5 grams of it out of your house.

      If you don’t already own a scale, invest in one. If you grow six plants, you will have much more than 28.5 grams. To stay legal, make sure you aren’t carrying too much at one time.

      Growing marijuana is your right

      Although it is now legal, many California home growers may need to stay stealthy. There are cities and towns in California that are prohibiting marijuana growing.

      Guess what?

      They are allowed to do that by this law. If you live in one of those areas, you cannot grow outdoors unless no one knows you are doing it. If they can tell you’re growing weed, you have broken the law.

      The law also says cities and towns cannot keep you from growing marijuana inside your home. This includes rental homes and apartments. If you are a renter, follow the rule of keeping your growing personal, and you will stay legal.

      California growing laws are highly defined, like California wine. Although they are more restrictive than other states, they also give a lot of rights to home growers. To repeat, if you need help, talk to a lawyer.

      California growing etiquette

      The right to grow weed at home is vital for many Californians. However, some things can get you in trouble, and likely piss off at least one of your neighbors.

      Here are some of them:

      • Growing more weed than you need – that’s not eco-conscious
      • Selling your weed – leave that to the ‘professionals.’
      • Planting outdoors where people don’t want you to plant – that’s just rude

      Medical marijuana users in California

      Starting in 2018, medical cardholders will not pay sales tax on retail weed. However, legalization may still be bad for medical users as it may restrict the availability of certain medical strains based on demand. This happened in neighboring recreational states.

      So, if you use medical strains, it is probably a good idea to start growing them now, before the supply diminishes (if you aren’t already).

      Prior to November 2016 California was well known for its medical marijuana program, and many California patients enjoyed the benefits of growing their own weed for medication. The state led the medical marijuana movement in the United States, with many states following their lead.

      The California program is approved for HIV/AIDS, Cancer, MS, epilepsy, Glaucoma, Chronic or unmanageable pain, Cachexia, Arthritis, and Migraines. in the past, you didn’t necessarily need a medical marijuana ID card to grow, but if you did, you risked getting arrested for illegal growing.

      You’d also need to:

      • Talk to a doctor about your condition. A doctor will need to write a recommendation. To find a California doctor, visit CANORML.
      • Download and read the Marijuana Grow Bible. This is the authority on growing the best marijuana. It will explain how to locate the right seeds and set up a grow room
      • Purchase. I Love Growing Marijuana has a large selection of marijuana seeds to choose from.
      • Check local Growing Rules. California Weed growing laws vary by city and county. Check the rules in your area here.

      The medical marijuana card

      You don’t need a medical marijuana card to grow California weed. Previously the card was useful for protecting growers from arrest. Patients and caregivers could register for the card with the state and show it to the police in the event of a possible arrest.

      For patients who prefer to remain anonymous, some nonprofits, as well as a few prescribing doctors, offer medical cards that are not registered with the state. These cards can provide proof of medical need but may not prevent a police officer from taking your weed.

        The laws have changed

        Growing marijuana in California used to be straightforward for those with medical approval. Before legalization, there weren’t actual limits on how much weed can be grown. This was unique to California.

        Basically,

        If you have a medical need to grow marijuana, the state assumed you will grow as much as you need.

        This wasn’t popular with everyone, however.

        Some areas in California challenged the idea, making it illegal to grow, or limiting collective grows. But for the most part, you were okay to grow if a doctor said so.

        Growing marijuana in California has been a thing for a while; so, it should be no surprise that there is still some confusion about how many plants medical users can grow.

        These things will get you in trouble

        There is one thing that you do not want to do as a marijuana grower in California. It should be obvious, but you should not try to sell your marijuana.

        Here’s what could happen:

        If you happen to sell your weed to a kid, you are facing felony charges. You also could be sued by the family member or employer of the person you sold it to. If you want to sell weed legally, go through the appropriate channels to be a legal marijuana business.
